Hi, MATHEMATICA has a built-in function JordanDecompose[] that can computes a Jordan normal form of a given matrix, and the related similarity matrix. Most importantly, it can obtain symbolic representations of these matrices, for a matrix given exclusively in terms of symbols (no concrete numbers, but symbols representing matrix elements). My question is: what kind of an algorithm is used by this function, in the symbolic mode of operation? I would appreciate references to the mathematical literature describing the algorithm. Leslaw
